水电厂机组可靠性分析与实际应用

Reliability Analysis of Hydro-turbine Generator Units and Practical Application

水电厂可靠性指标是衡量机组运行、检修及故障停运情况的重要指标。文章基于高坝洲水力发电厂2012-2021年机组运行的可靠性指标统计数据表明,近十年设备维护得当,机组运行稳定可靠,为电网安全稳定运行提供了有力保障。同时从管理方法上分享了提高机组可靠性有效途径,可供同行借鉴。

The reliability index is an important indicator for evaluating the operation,maintenance and fault shutdown conditions of hydro-turbine generator units.The statistical data of the unit operation reliability indicators in Gaobazhou Hydropower Station from 2012 to 2021 is analyzed.The results show that the units have been maintained properly and operated stably and reliably in the past decade,providing strong guarantees for the safe and stable operation of the power grid.Also,some effective approaches to improve the reliability of the units are shared from the perspective of management,which can be useful reference for other hydropower stations.
